i think it is only a little bit coincidental that without humans, everything would still exist except, instead of humans giving all this meaning to it (and requiring narrow minded people to retreat behind the veil of "god" because the scope and size of the universe is massive and therefore short-circuits many people's brains) everything would just EXIST. the universe has no purpose, if a conscious being (god for example) existed and created the universe the universe would have a purpose, all conscious thought does- that is the dictionary meaning (seeing we all like to be so anal around here). if this conscious being created the universe it was created for a reason- that is not the case. remove humans from the equation (seeing we are the only species with conscious thought) and the universe has no purpose, the only reason we think it has purpose is because we like to think we are important. so, include humans into the equation and you have the same outcome- there is no purpose behind the universe, we would just like there to be purpose so we can try to comprehend the universe and think that we are not here without a purpose. that is what is most distressing, the thought that we have no purpose- and we don’t- is an idea very few would like to entertain and therefore god comes into the equation to ease people’s discomfort.
